Expert Response
From the photos it looks like you may have rose chafers. You should be looking for the adults for a certain diagnosis.
Below are a couple of articles on how to manage them. You apparently have a large infestation. They are most prominent in areas with sandy soil.
If you choose to use a pesticide, be sure to identify the pest first. Follow all label instructions and wear protective clothing. Avoid spraying when bees are out.
